Silver lining? Greenhouse gas could be vast, untapped source of energy

The greenhouse gas carbon dioxide emitted from power plants and other industrial activities around the world is a vast source of untapped energy, according to new research that describes a proof-of-concept technique to harvest it.

Akin to harvesting energy from the wind, this combination of chemistry and mechanics would generate electricity from the carbon dioxide (CO2) already flowing out of plants. While it wouldn’t destroy the CO2, it would pull far more energy from existing waste gas. It could arguably even enable plants to resist scaling up and becoming more wasteful, just to keep up with demand.
